The aim of the invention is to improve the primary detergent power of washing and cleaning agents, in particular with respect to bleach-sensitive or enzyme-sensitive soiling. This is substantially achieved by the incorporation of alkoxy group-carrying sulfocalixarenes or carboxycalixarenes.

their surfactant abilities, and the effects of water amount used and reaction durations on the catalytic activities of these amphiphilic calix[n]arene derivatives were also investigated. Observations indicated that these amphiphilic calix[n]arene catalysts exhibited high catalytic activities in the coupling reactions of 2-methylfuran and N-methylindole with some alcohols in water.
